  • the present invention relates to a bulk battery, in particular a bulk battery suitable for incorporation into a material torrefaction process.
  • the newly proposed device falls by its design into the field of transport and storage equipment and by its use into the field of power generation, actively complementing in particular solar, wind and other power plants.
  • the prior art described below relates to various technologies, namely bulk storage, energy storage and thermal material processing.
  • Hoppers are generally devices that are used to store various materials. In practice, these devices are well known and widespread in various industries such as construction, agriculture, food processing, etc. They are usually placed above the ground level by means of beam structures and the earth's gravity is used to empty them, which allows, if the storage device is properly designed and set up, the spontaneous discharge of the material without the supply of additional energy. At the bottom of the hopper, there is a discharge cap equipped with a device for opening and closing the output. When the material is discharged from the hopper, the material has kinetic energy which is not currently used in these devices. Thus, the primary use of hoppers in the prior art is to store bulk material, which can then be returned to the production and use processes.
